I think the decorator part is reasonable in testing and prototyping.

Every layor of some decorator just adds more overheads, therefore, 
the syntax sugar of the symbol @ just reminds the programmer the fact.

Acctually writing better wrappers for non-trivial enhancements
to objects or functions should be practiced by professionals.

It is easy to import objects written by others in python. 

It is also user responsible to test and enhance the objects 
from others by decorators, the unittest module, or whatever suitable.


I love to play with functions with a varable representing the time
in writing computer games that emulate  hundreds  to thousands of 
animated obects.
